These 0.3mm PCBs are crazy flexible. Makes it difficult to evenly polish down to extract all the metal layers, but we'll fix it in post 😉

The low cost fiber laser optic is now ready! Only based on COTS, around 2um spot when coupled to a 980nm laser, 100mm working distance, 75% of power transmission; less than 180€. Can be mounted in most CNC routers / 3D printers.

Here's a test shot of the backside of an AMD M74AP I took while calibrating some new gear over at https://t.co/o2HeER5TiI Blog post and source coming soon!

Over the summer, I got nerd sniped with extracting bits from microscope photographs of mask ROMs. Here is my C++/Qt6 CAD tool for marking and extracting bits, including Design Rule Checks, a variety of export formats and a CLI. https://t.co/1TXIyhMVm9

Some examples of how we too often get wrapped up in complex attack chains that show off our “skills” that we overlook the glaringly obvious 🤦♂️
@BronsonGhost Reminds me of an old conference talk by @0x31337 at Toorcon (I think?) where he outlined a complex attack against parking meter cards and some other things only to admit at the end, if you shove a folded business card in the slot, it goes "out of order" and you won't get ticketed

DES Rainbow Tables for NetNTLMv1 coming soon. Thanks David!
@NotMedic @tiraniddo @SkelSec @UK_Daniel_Card I’ve got a friend that’s working on writing GPU support for the tables and finally have all 6TB of them up in our toor rack so hopefully will be publishing them soon for everyone to use 🤞

I must say, https://t.co/hXzDGvrjSg is pretty impressive. 45 seconds for a NTLMv1 hash :) Of course if anyone can tell me what the password was I'd appreciate it, seems I've forgotten😂

I'm happy to announce my new book, Open Circuits! Windell Oskay and I painstakingly cross sectioned, cut, sanded, polished, and cleaned over 100 electronic components and took sumptuous photos. Check out the sample chapter! https://t.co/AquBAwTJIw

\o/ I’ll show our research on how to go from a crypto design to the list of gates that leak, automatically. Come learn about side channels, hardware design, and a little story about the AES core that thought it was secure.
In August 2022, join us at BlackHat in the USA where the CTO of Riscure North America Jasper van Woudenberg (@jzvw) will present "Whip the Whispers: Simulating Side Channel Leakage." Learn more about the talk and register to attend here: https://t.co/m1Vr71E8TB. See you there!

This orange plasma display is being powered by just enough voltage to create a dim glow, but the 405nm laser pointer pushes certain areas into a higher output, which remains until power cycled! A plasma Etch-A-Sketch.
